Dredge America

Abstract

Dredge America was selected as the most qualified contractor to perform marsh restoration services for the Blackwater National Wildlife Refuge (NWR).

The project, located in Cambridge, Maryland capitalizes on the experience and expertise Dredge America gained from the Prime Hook Restoration Project.

Dredge America helped restore the natural salt marsh using a thin layer deposition method of dredging. By spraying “dredge material” over the existing marsh surface, we raised the existing marsh platform to provide plant resiliency, combating rising sea levels at the site.

Our goal for the project was to remove and place approximately 26,000 cubic yards of sediment to restore up to 30 acres of the fragile marsh habitat.

Completing the first large-scale wetland restoration project ever attempted at Blackwater, and the first thin-layer project in the Chesapeake watershed, the restoration was a resounding success, having been completed on time and under budget.

The non-profit owner, The Conservation Fund, in partnership with the U.S. Fish and Wildlife Service(USFWS), are extremely satisfied with the results.
